1 = the old RmXP/RmVX Autotile 2 = the new Tilemap Autotile 3 = Full transparent and half transparent Color (color picker mode) 4 = The live preview wich shows an ingame constalation of the Autotile. (all the Autotiles and the Preview are shown animated)
The Color Picker mode. It took some time to manage the pixel_to/for things.. But it´s working now. The Function of this mode duplicates each pixel to a double-size bitmap to show it 2 times bigger (easier to click). And the small rectangle shows the actual color, wich is under the picker-cursor.
